2 Claims.

The invention relates to the improvement of water tight containers,receptacles and boxes which are built of sheet metal and more especiallyto those built of heavy gauge sheets and metal 5 plates; and the objectsof the improvements are first, to minimize construction joints; second,to simplify construction; third, to construct from one piece of metal;fourth, to reinforce and stiffen where the strain is greatest; fifth, tomake as light in weight as possible; sixth, to insure quick and easycleaning; seventh, to facilitate handling.

My invention relates broadly to all water tight containers, receptaclesand boxes having a bottom and four walls (2 end walls and 2 side walls)which are built of metal, and more particularly to those which areconstructed from one piece of metal, especially where the end walls arecurved upwardly and outwardly from the bottom and. where one or more ofthe walls terminate in outward flanges, and to the attachment of metalstraps to such metal containers, receptacles and boxes.

One formof my invention is illustrated in the two accompanying sheets ofdrawings, in which Figure 1 is a plan View of the sheet of metal ormetal plate before bending to shape; Figure 2, a plan view after bendingto shape; Figure 3, a bottom View after bending to shape and showing onearrangement of attaching metal straps; Figure 4, a side view afterbending to shape; Figure 5, an end View after bending to shape; Figure6, a diagonal view of superimposed flanges at point B; Figure 7, an endview of superimposed flanges at point B; Figure 8, a side view ofsuperimposed flanges at point B; Figure 9, a cross section taken at A toshow manner of looping metal straps.

By referring to- Figure 1, it will be noted that a single piece of sheetmetal or metal plate aa aa is cut in any manner along the solid linesbcdd'cb-bcddcbto form a blank from which, if divided into sections, Lwill become the bottom; M, thetwo end walls; N, the two side walls; and0, the flanges of the metal container, receptacle or box.

Sections N, are then bent upward along broken lines c--c to form the twosides. Next, sections M, are bent upward from broken lines -0 and insuch manner that the plane surfaces, or short axis, of sections M, alongthe solid lines c-d, shall become curved, such curve to fit snuglyagainst the curve already out along solid lines cb, and thus to form theend Walls of the metal container, receptacle or box.

The flanges O, are next bent outwardly and the projecting ends 12, aresuperimposed upon the projecting ends d, as is admirably shown in largesize Figure 6. Also, large size drawings of this superimposing offlanges is shown in end View Figure 7, and side view Figure 8.

It is then, after bending to shape, that the construction joints arewelded, soldered or otherwise made fast along lines c-bd and thesuperimposed flanges along their lines of contact. A plan view, afterthe four walls and flanges are bent to shape and placed in position isshown in Figure 2.

It is understood of course that this sequence of operation is only forconvenience of explanation for the same results may be accomplished thruother sequences and it is essential only that the completed productshall be as detailed herein and/or illustrated in the accompanyingdrawings.

In order to facilitate handling of large or heavy metal containers,receptacles and boxes one or more metal straps may be spot welded,soldered or otherwise attached to the same, and one location of suchstraps is parallel to the long axis as is shown in bottom view Figure 3.Such metal straps may have one or more ends looped as is distinctlyshown in large size section Figure 9.

Referring again to bottom View Figure 3, it will be noted that I havehere, and in end view Figure 5, shown straps e--e to be looped at bothends and strap ff not looped at either end. But, the looping of the endsof straps is purely optional and none, one, any or all ends of strapsmay be or may not be thus looped. It is to be understood that thesemetal straps are not required by my invention in order to make the samecomplete, as the metal container, receptacle or box as invented by memay be successfully used with or without the metal straps.

It will be noted that my invention admirably simplifies the constructionof water tight containers, receptacles and boxes formed from one pieceof metal to such an extent that only four joints are required to bewelded, soldered or otherwise made fast. The flange amply reinforces andstifiens the four walls and the superimposing of the ends of theseflanges after they have been properly welded, soldered or otherwise madefast, fixes the construction joints permanently and rigidly in place.Thus, all excess weight is eliminated and the handling of large or heavymetal containers, receptacles and boxes is facilitated by attachingmetal straps. Quick and easy cleaning is assured by the two upwardcurving end walls and the natural curves caused by bending of metal tothis design.

I am aware that prior to my invention containers, receptacles and boxeshave been built from one piece of metal. I therefore do not claim suchconstruction broadly; but:

5 I do claim:

1. A container of sheet material comprising a bottom, side and endwalls, said side and end walls being provided with outstanding marginalflanges, laterally spaced reinforcing straps se- 10 cured to andextending along the bottom and end walls of the container, certain ofsaid straps I the container a pair of handles.

2. A sheet metal container having bottom, side and end walls, said sideand end walls being 5 provided with outstanding marginal flanges, andsaid end walls being curved, and reinforcing straps extending along thebottom and end walls of the container and terminating in loopsimmediately beneath the flanges of the end walls. 10
